Morrissey's new role sees him cast as Lewis Bernt, an air safety official caught up in a mysterious plane crash.

The 49-year-old will be "doing double duty" on The Walking Dead and the Line of Sight pilot, AMC told Deadline in a statement.

"We are huge fans of David Morrissey and are glad he'll be doing double duty for AMC viewers through his work on The Walking Dead and our pilot for Line Of Sight, both of which are produced in Atlanta," said the broadcaster.
